My Minimax 16 bandsaw (about 12 years old, 5 hp, 3/4" Timberwolf blade) has been shutting itself off without being under heavy load, without overheating, and without activating the magnetic switch to the safety position. It starts right back up when the button is pushed. Tried adjusting bearings, cleaning them, reducing blade tension. It runs on its own 220 circuit, and cuts out whether or not the dust collector is on (on its own 220 circuit). It has never done this before, but some years ago did replace the switch because it was obviously malfunctioning. Not likely to be the door kill-switches, because the saw restarts immediately .
Any ideas appreciated. Is it possible my voltage has changed ? Once in a while, the 3 HP Oneida DC shuts off, and it also restarts right away.
